Excerpt

Bumpers still offer high lightweight design potential in the vehicle front end. A new bumper system with a hot-formed steel crash beam which is 19 % lighter than the reference solution with comparable costs is being developed as part of InCar plus. This means that the weight of average aluminum solutions will be achieved at significantly lower cost. Modular and roll-formed sectional crash beams have also been developed. These are up to 17 % lighter and offer the advantage of cross-fleet flexibility. Thanks to new grades of steel, weight reductions of around 13 % are possible in the crash boxes. The results are rounded off by a bumper concept which can be easily integrated into existing vehicle structures and coordinated with the IIHS small overlap rigid barrier (SORB) load case. …
